There is no actual turn signal relay. I think you mean the turn signal flasher. This is the part that actually causes the signals to flash. It does look like a relay though. The flasher part number is(NNN) NNN-NNNNand goes for $55 from the dealer. Is this what you purchased? Please reconsider changing my rating to good or better.

See below for all info regarding the turn signal system:

It is plugged into the Junction Block at position 4, where all wiring associated with its operation is terminated. The Junction Block is adjacent to and left of the steering column of the vehicle. To gain access to the flasher, remove the lower steering column cover and knee blocker.
The ignition input to the combo-flasher will draw typically 5 mA of current while active.
